pin descriptions and functions p in o ut p ositive i nput and i nput c ommon steady state voltage range is 16 to 40 vdc. transient range is 40 to 50 v for a maximum of 120 msec. low voltage lockout prevents the units from operating below approximately 15.5 vdc input voltage to keep system current levels smooth, especially during initialization or re-start operations. all models include a soft-start function to prevent large current draw and minimize overshoot. c ase and e xternal i nput f ilters internal 500 v capacitors are connected between the case and input common and between the case and output common. see figure 1. interpoints fme filters are recommended to meet ce03 require- ments for reflected input line current. when using an external input filter it is important that the case of the filter and the case of the converter be connected through as low as an impedance as possible. direct connection of the baseplates to chassis ground is the best connection. if connected by a single trace, the trace should be as wide as it is long. t rim both single and dual output models include a trim function. output voltage can be trimmed from 60% up to 110% of nominal v out . when trimming up, do not exceed the maximum output power. when trimming down, do not exceed the maximum output current. on dual models the positive output is regulated and the negative output is transformer coupled (cross-regulated) to the positive output. when trimming the duals, both output voltages will be adjusted equally. i nhibit 1 and 2 two inhibit terminals disable switching, resulting in no output and very low quiescent input current. the two inhibit pins allow access to an inhibit function on either side of the isolation barrier to help maintain isolation. an open collector is required for inter- facing with both of the inhibit pins. applying an open- collector ttl logic low to either inhibit pin will inhibit the converter. applying an open collector ttl logic high or leaving the pins open will enable the converter. inhibit 1 is referenced to input common, while inhibit 2 is referenced to sense return on the output side. the open circuit voltage for inhibit 1 is 13 v and for inhibit 2 it is 8 v. float the inhibit pin(s) if not used. the required logic low voltage level is 0.2 v maximum. pin single output dual output 1 positive input positive input 2 input common input common 3 trim case 4 inhibit 1(inh1) inhibit 1(inh1) 5 sync out sync out 6 sync in sync in 7 positive output positive output 8 output common output common 9 sense return negative output 10 positive sense trim 11 share share 12 inhibit 2 (inh2) inhibit 2 (inh2) 5 mor series 120 watt dc/dc c onverters 20 k 200 ? 10 k v cc positive input inhibit 1 input common mor input side 12 v f igure 5: i nhibit ?i nput s ide v s ~ ~ 10 k 200 ? current limit feedback voltage e/a inhibit 2 sense return mor output side f igure 6: i nhibit ?o utput s ide positive input 1 2 input common mor single or dual output 10, 11, 12 7, 8, 9 case* chassis ground positive input 1, 2, 3 4, 5, 6 28v input common fme28-461 emi filter positive output output common f igure 2: e xternal f ilter c onnection 3 trim r t 7 10 9 8 positive output positive sense sense return output common mor single output trim up trim down f igure 3: t rim ?s ingle 10 trim r t trim up trim down mor dual output 7 8 9 positive output output common negative output f igure 4: t rim ?d ual trim down: = , 0.6 1.0 v o v o nominal example: v o nominal = 5.0 , v o = 4.5 , = 0.9 , r t = 150 k ? r t (k ? ) = 50 30 1 trim up: = , 1.0 1.1 v o v o nominal example: v o nominal = 5.0 , v o = 5.25 , = 1.05 , r t = 390 k ? r t (k ? ) = ( 1 ) 20 ( -1) 2.5 v o 50 trim formulas
